TM 9-2350-277-20-2PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS), INCLUDINGLUBRICATION INSTRUCTIONS — Continued0155 00g.USE OF TORQUE WRENCH ADAPTERS AND THE CONVERSION FORMULA.1) The torque values given in the text of this manual are the actual values that must be applied to the nut or screwfor proper maintenance.2) Some tasks require the use of a torque wrench adapter when the nut or screw cannot be reached with a regularsocket on the end of the torque wrench. When an adapter is used on a torque wrench, definite rules must befollowed or the nut or screw will be over- or under-torqued. The center line of the adapter should be used inone of two positions:a) One position is to have the adapter center line at right angles to the center line of the torque wrench. Inthis position, the indicator reading does not have to be calculated and it may be read direct.b) The other position is to have the center line of the adapter in line with the center line of the torque wrench.In this case, the adapter adds to the overall length of the torque wrench and makes the dial or scalereading less than the actual torque applied to the nut or screw. To prevent overtorquing and damage toequipment, you must calculate a corrected dial or scale reading.0155 00-5
